laughlin Posted February 21, 2018 Report Share Posted February 21, 2018 I've got a bisqued mug with a lot of various underglazes layered over textures on the outside, it's nice. I'm unhappy with the solid underglaze blue on the handle and inside - it wants 'ageing'. Will bisqued underglaze take a watered down underglaze wash OK? And for future reference, what about painting undiluted coats of underglaze on bisqued underglaze? I've only used UGs on greenware. I'll be glazing with the usual clear. Thanks!

Gabby Posted February 22, 2018 Report Share Posted February 22, 2018 I think some underglazes are designed to work as well on bisque as on greenware and some not. The underglazes I use work equally well on greenware and bisque. I prefer to underglaze on greenware, because if I underglaze and then glaze in the same stage, on bisque, the clear glaze can smear the underglaze.

neilestrick Posted February 22, 2018 Report Share Posted February 22, 2018 Most commercial underglazes will work fine on bisque. As long as they haven't glossed over, they'll take more underglaze just fine. Whether or not the covering glaze will move the underglaze depends on the glaze.

laughlin Posted February 22, 2018 Author Report Share Posted February 22, 2018 Thanks! I knew they'd work on bisqued clay, glad to hear that extends to *underglazed* bisque. More room to fiddle is always good. Quote Link to comment Share on other sites More sharing options...

Another approach to aging the handle is to take a walk outside with some sand paper and an x-acto knife and scratch and sand away some of the under glaze. Use fine sand paper at the end to get rid of any jagged spots. You can still add a wash to this afterwards if it needs it. Link to comment Share on other sites More sharing options...
